LOCK FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 300,743, dated June 17, 1884.

Application filed March 24, 1884. (No model.)

To aZZ whom it may concern:

ie it known that I, J osEPn 'Vic'ron, a citi zen of the United States, residing at Duquoin, in the county of Perry and State of Illinois, have invented certain new and useful Improvements in Locks for Fire-Arms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to locks for fire-arms; and its object is to provide an improved lock possessing advantages in point of simplicity, strength, durability, and general efficiency, and which may be operated or manipulated with facility and convenience aml with perfect safety.

To this end my invention consists, substantially, in arranging the mainspring and connecting it with the hammer so that it effects the cocking of the same when the rear ends of the barrels are elevated, and also serves as the barrel-check in the arrangement of a safety block for the hammer, the block being eonnccted with and operated by the trigger, and in an automatic trigger-lock connected with and operated by the lever which locks the barrels in their normal position, so that when this lever is operated to admit of the dropping of the barrels the trigger-leek is released and automatically engages the triggers, substantially as will be hereinafter more fully set forth, and partieularl y pointed out in the claims.

In the drawings, Figure l is a side elevation illustrating my improved locking mechanism in cocked position and with the rear end of the barrels elevated. Fig. 2 isa corresponding view showing the barrels and look ing mechanism in their normal position. Fig. .i is a detail perspective view showing the hammer, trigger, and safety-block mechanism. Fig. iisa detailperspective view of the safetyblock. Fig. 5 is a detail top view of thelever for operating the safety-bloek. Fig. 6 isadetail top view of the sear of the lock. Fig. 7 is a detail perspective View of the trigger-lock plate. Fig. 8 is a detail perspective view of the head of the automatic triggerdoek. Fig. 9 is an inverted-plan view in detail, illustrating the relation of the spring-catch belt of the automatic trigger-locking mechanism with the tumbler of its operating-lever.

Corresponding parts in all the figures are denoted by the same letters of rcl'erence.

Referring to the drawings, A designates the working body, B the barrels, and U the pivoted fore part of the working body, to which the barrels are secured, these parts being in the main of any suitable construction.

1) is the maiuspring, which is pivoted in a suitable recess in the side of the body A, and has its front end, (I, proieeting into a recess, 0, provided in the fore part, The reareml of this spring-lever engages with a suitable notch, c, in the hammer i so that when the barrels are dropped to elevate their rear ends the fore part, 0, carries the front end of the said spring-lever in its downward movement, thus causing an upward movement of the rear end of the springlcver, and thereby effecting the cocking of the hammer by causing it to engage with its sear. The barrels may then be closed down to their normal position against, the tension of this lever-spring l). The front end, (I, of the maiuspring l) is preferably turned downwardly. as shown, so that it approximates ahook shape which is best adapted. to the movement of the said end, as it is carried by the fore part, (I, and the bottom of the recess 0, which receives the end (I, is preferably curved or rounded. The mainspring is pivoted or fulerumed j ust in rear of its end d, to effect a greater leverage upon. the hammer, and it is provided with a projecting portion, (1, above its fulcrum, which is :nlapted to engage with the top of the recesses in which the lever is fulcrumed, and thereby serves as a check to limit the dropping of the barrels. From this arrangement it will be seen that the spring-lever I) performs the functions of a mainspring, a barrel-check, and automatically effects the cocking of the hammer.

The scar F of the lock is pivoted upon the body A, and its front end is adaptedto engage the notch 13" of the hammer,to retain the same in locked position. Thus, when the rear end of the sear is elevated by the trigger (it, its front end releases the hanuuer and the discharge is effected by the tension of the leverspring 1).

To guard against discharge by the aceidental release of the hammer, either before or after the barrels are completely returned to their normal position, a safety-block, H, is arranged to slide vertically in front of the hammer and in a suitable guide-groove formed in the body A. This safety-block is normally under the nose 0* of the hammer, asillustrated in dotted lines, Fig. 2 of the drawings, and when the hammer is cooked to the position shown in Fig. 1 the block automatically moves up in front of the nose, so that if premature release of the hammer occurs from any cause its nose will engage the safety-block and there will be no discharge of the load. The safetyblock is operated by a lever, I, having its front end engaging a notch, h, in the block, and adapted to have its rear end elevated by the trigger. Thus when the trigger is operated, the lever I will force the safety-block downward simultaneously with the disengagement of the sear from the hammer, and the gun will be discharged. A coiled spring, J, is interposed between the scar and this lever I,to return the parts to their normal position, the said spring being arranged in front of the fulcrum of the lever I in rear of the fulcrum of the sear.

K designates the trigger-locking plate, which is adapted to slide longitudinally upon a guidepin, L, and engage shoulders g in the rear edge of the triggers. This plate is connected with a sliding headpiece, ill, by means of alever, N, having its ends engaging suitable notches, k m, provided, respectively, in the locking-plate and head-piece. The head-piece works through the top of body A, and is provided with a milled head, m, by which it may be operated to force a longitudinally-sliding spring-bolt, 0, forward, so that the end of the same will engage a shoulder, 11, formed upon a tumbler, 1, secured to the pivot of the locking-lever (,3. A spring, R, is arranged to act upon this tumbler to retain the lever in its normal position for locking the barrels in position. The bolt 0 slides in suitable brackets, S S, upon the body A, and a coiled spring, T, is arranged to force the bolt rearwardly. A spring, U, may also be arranged in rear of the head M, to prevent the same from accidentally slipping rearwardly and locking the triggers.

3y this arrangement, when the bolt 0 is engaged with the tumbler P, the locking-plate R will be out of engagement with the triggers. Then when the lever Q is turned to permit the barrels to drop and the hammers are cooked by this movement, the bolt will bereleased from the tumbler and the trigger locking mechanism will automatically move into engagement with the triggers and lock the same. \Vhen it is desired to discharge the gun, the head-piece M is moved forward with the thumb to force the bolt into engagement with the tumbler P, and to thereby draw the lockingplate from its engagement with the trigger.

It will be understood that in the ease of double-barreled fire-arms, as herein shown, eaehhammcr is provided with afspring-cocking lever and sear, and with an independent safety block mechanism operated by independent triggers; but both hammers are cocked by the one movement of dropping the barrels, and the single trigger-locking mechanism effects the locking of both triggers.

The operation and advantages of my invention will be readily understood from the foregoing deseription and annexed drawings. By pressing the locking-lever to the right the ban rels may be dropped to elevate their rear ends, which movement automatically effects 7 the cocking of the hammers, by the action of the mainsprings. Simultaneouslywith the cocking of the hammers the safetyblocks slide up in front of the nose of the hammers, and the trigger-locking mechanism engages the triggers. After the shells are placed in the gun, the barrels are closed down to their normal position, and the head of the trigger-locking mechanism is moved forward to draw the locking-plate from its engagement with the triggers, when the gun may be discharged.

ll am aware that amainspring has been heretofore pivoted on the frame between the hammer and the pivoted fore end,with its rear end engaging the hammer, and its front end received by the pivoted fore end, whereby the spring is operated to cook the hammer by the dropping of the barrels. I therefore do not broadly claim such invention.
